| 摘要 |
<p>The present invention generally relates to absorbable, crystalline, monocentric, polyaxial copolymers having a crystalline component, and a flexible, amorphous com-ponent. More specifically, the invention relates to such copolymers wherein the flexible and/or the crystalline component of the polymer comprise lactide units. The invention also relates to a method of producing such copolymers, and products thereof, as well as a polymeric, polyaxial initiator, having at least three axes originating and extending outwardly from the centre of the initiator, said centre being formed from an at least tri-functional initiator molecule, containing lactide, which initiator can be used in pre-paring the copolymer. The copolymers of the invention exhibit improved mechanical properties such as improved compliance, and prolonged mechanical integrity in vivo.</p> |
